Youlean Software

High-Quality Audio Software For Professionals.


I’m Julijan Nikolic. (You may know me as Youlean). I am the developer behind Youlean Loudness Meter.

In 2016, I created Youlean Loudness Meter as part of the KVR Developer Challenge (create the best free audio software).

To be honest, I was already fascinated with the new loudness measurement techniques but I was a bit stunned when I realized how expensive these types of plugins are. That was the moment I decided to build it by myself.

The proof that people loved it came really quickly – Youlean Loudness Meter was voted a clear winner of the KVR Challenge 2016.

After many lines of code and many hours, days and months later, I was able to bring to the users a new PRO version which implemented many useful options that will save your time and improve your workflow. Also, the PRO version will help me to fund the future updates for Youlean Loudness Meter and other plugins too!

Thanks everybody for your support!

Lifetime Free Updates

“I love audio software, and there are some really cool companies and really cool plugins, but man, there is no worse feeling in the world when you need to PAY for the bugfixes i.e. updates. I really hate that, and I really hate that this is the way most of the audio companies do the business.

This is not how I want to sell the software and that’s why I guarantee the lifetime free updates.”

Price Below the Average

“Once I learned about loudness metering using LUFS, I was really fascinated. The problem was that the plugins for measuring it were (and still are) really expensive and there were no free ones that can get you started.

So, I have decided to create a free loudness meter that will be even better than the most expensive ones.”

The First VS The Latest Version

The first version of Youlean Loudness Meter

* Released on December 1, 2016

The latest version of Youlean Loudness Meter

* Released on February 14, 2021

The Latest Update

There are a few small improvements though, like adding a warning when the sample rate is not correct for the standalone app. That was the most common issue for the app not measuring the live inputs.
Also, I have finally simplified the buffer settings for the app (it’s not like you really needed to tweak it in the first place). The view menu icon is changed too since many of you didn’t even know that there is a menu inside. I hope it is more clear now.

I needed to drop support for macOS 10.8 in order to add support for Apple Silicon processors. Now the minimum supported OS is macOS 10.9.
This is due to Apple forcing devs to use the new standards which is definitely pushing an industry forward, but it requires constant upgrading of OS in order to run the latest software. This is why many of the new plugins work only on macOS 10.12 or higher. Keep that in mind when selecting a computer for the studio.

As for bug fixes, most notably, I have fixed the GUI flickering on some old macOS versions, fixed default preset loading, and app forcing usage of dedicated GPU on some mac machines.

Loudness Standards – Full Comparison Table

Mastering audio these days needs to touch the loudness standards. This can be confusing since requirements differ from service to service, so I wanted to create a simple table containing all presets that are included in the Youlean Loudness Meter so you can easily find out what you need to do.

The table contains the official recommendations for different services. If you follow these recommendations you won’t have any trouble.
